Worksheet Worksheet 4
1.
Fill in the appropriate value into the boxes, then use the method to factor the given quadratic polynomial using a complete presentation.
\begin{equation*}
3x^2 - 10x - 8 \longrightarrow \left\{
\begin{array}{l}
\text{Multiply to $\boxed{\strut \phantom{.....}}$} \\
\text{Add to $\boxed{\strut \phantom{.....}}$}
\end{array}
\right.
\end{equation*}
2.
Use the \(ac\) method to factor \(x^2 + 6x + 9\) using a complete presentation.
3.
Use the \(ac\) method to factor \(x^2 - 3x - 40\) using a complete presentation.
4.
Use the \(ac\) method to factor \(2x^2 - 5x - 3\) using a complete presentation.
